HEADLIGHT.

Specification of Letters Patent.

Patented May 24, 1921.

To all whom it may concern:

Be it known that I, HARRY F. HAMMOND, a citizen of the United States, and a resident of South Shaftsbury, in the county of Bennington and State of Vermont, have invented a new and Improved Headlight, of which the following is a full, clear, and exact description.

This invention relates to improvements in headlights, an object of the invention being to provide in the ordinary headlight an improved arrangement of partition or partitions having dull surfaces which operate to prevent direct glare but give full road illumination.

It is a well known fact that headlights which give the necessary road illumination also give an intense glare which is blinding to approaching vehicles and it is the purpose of my invention to provide an attachment which can be used with ordinary headlights and which will give the necessary road illumination and at the same time greatly reduce, if not entirely eliminate the glare.

With these and other objects in view the invention consists in certain novel features of construction, and combinations and 'arrangements of parts, as will be more fully hereinafter described and pointed 'out in the claims. y

In the accompanying drawings- Figure 1 is a View in front elevation of a headlight, showing one form of my invention therein;

Fig. 2 is a view in section on the line 2-2 of Fig. 1;

Fig. 3 is a perspelqc tive view of the double Fig. 4 is a view similar to Fig. 1 illustrating a modification;

Fig. 5 is a perspective view of the single partition shown in Fig. 1; and

Fig. 6 is a fragmentary view in section on the line 6-6 of Fig. 1.

1 represents the shell of the headlight, 2 the glass or lens in the front thereof having a holding rim 3, and 4 is the reflector, in

the center of which a lamp socket 5 is pro vided to receive an .electric lamp 6. The aboye described headlight is the common type in ordinary use and it is the purpose of my invention to provide an attachment which can be used on an ordinary headlight.

The reflector 4: is of the ord nary parabolic shape and the lamp 6 is at the focal center thereof, and my improved attachment illustrated in Figs. 1, 2 and 3, consists of a pair of crossed partitions 7 and 8. These partitions are located at right angles to each other and are of a shape throughout one edge'to fit the parabolic shape of the reflector 4. The partitions 7 and 8 are re-- cessed as shown at 9, to accommodate the lamp 6 and at their outer edges are provided with lugs 10-which are projected through openings 11 in the shell of the lamp.

The inner-ends of the partitions 7 and 8 are connected to a ring 12 which fits around the lamp socket 5 and to facilitate the removal and the replacementof the lamp 6, one section 13 of the partition 8 is movably connected with the other portions of the partitions, as will now be described.

This section 13 has a movable connection at 14 with the ring 12 and at its outer portion at its inner edge is formed with angular lugs 15 which engage metal loops 17 on the partition 7 By moving this section 13 outwardly the lugs 15 can be freed from the loops 17 and the section 13 can be swung outwardly to permit a lamp to be positioned in the recesses 9 and then together with the partitions can be moved into the reflector 4 and screwed into the socket 5.'

In the modification illustrated in Figs. 4 and5, a single horizontal partition 18 is provided. This partition has lugs 19 at its ends corresponding to the lugs" 10 of the preferred form and is provided With a lamp receiving recess 20 and a ring 21 to fit over the socket 5 in the headlight.

All of the partitions are opaque and are preferably of metal, such for example, as aluminium, although they may be made of any suitable material which has a dull sur-- face. This dull surface of the partitions operates to dim the light which is thrown thereon by the surfaces of the reflector 4. In other words, the partitions throw back the light upon the reflector and cause a dimming action on the light from the lamp 6.

This dimming action is mainly applied to without materially afi'ecting theroad illumination. a r

Various other slight changes may be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself at liberty to make such changes and altera tions as fairly fall within the spirit and scope of the appended claims,

' I claim:

1. lhe combination with aheadlight, a parabolic reflector in the head light, a lamp socket at the focal center ofthe reflector, and a lamp in the socket, of a horizontal opaque dull surfaced partition fitting the reflector and located centrally thereof, said partition having a recess therein conforming to the shape of the lamp, a fixed ring positioned transversely of the partition and fitting around the lamp socket, and integral outwardly and rearwardly projecting lugs at each side of the forward edge of said partition locking said partition in position.

2. The combination with a headlight, a reflector in the headlight, and a lamp at the focal center of the headlight, of a pair of crossed partitions fittings'aidreflector, one of said partitions comprising a pair of sections and one of said sections removably connected to one of said partitions whereby removal of said section permits access to the lamp. p 3. An attachment of vthe character de-' scribed, comprising drossed partitions at ri ht angles to each other, one section of HARRY F, HAMMOND.
